Overwrite the characters with your desired name.
Open and navigate to Connected Devices or Bluetooth .
Open the saved binary file in a hex editor like HxD.
Be cautious when attempting firmware changes; incorrect settings can "brick" the module, making it unable to connect.
To change the name, you must overwrite this specific data segment. This is achieved either via a dedicated PC configuration tool connected through a USB-to-UART serial adapter, or by directly flashing the memory chip using an EEPROM programmer. Vhm-314 Change Name
While you cannot change the module's broadcast name, you can manage the confusion. The most direct method is to simply rename the device (phone or computer). In both Android and iOS, you can rename any paired Bluetooth device to something meaningful like "Workshop Speaker" or "Living Room Hi-Fi". This is a cosmetic fix that only helps you.
Open the JieLi configuration utility on your PC. These proprietary tools feature a graphic user interface (GUI) dedicated to editing fixed chip parameters: Power on the VHM-314 via the USB adapter.
Open NeoProgrammer, click "Detect" to identify the chip type, and click "Read IC" . Once the read completes, click "Save" to backup the original firmware as a .bin file. Never skip this step; you will need this backup if the chip data becomes corrupted.
The name change is intended to [briefly explain the reason for the name change, e.g., "reflect a change in branding" or "align with updated regulatory requirements"].

Complete Guide to Renaming Your VHM-314 Bluetooth Audio Receiver
JieLi standard flashing/debugging tool (often called "JL Isptool" or the "JieLi Bluetooth Burning Tool"). Step-by-Step Process:
Because hardware and firmware modifications carry a risk of bricking the cheap board, utilizing client-side Bluetooth aliasing is the safest and most efficient solution for the majority of users. Instead of changing how the VHM-314 transmits its name, you change how your receiving device displays it. On Android Devices:
Acquire a Bluetooth audio module that supports standard AT commands via a serial interface (UART).
: Go to Settings > Bluetooth , tap the "i" icon next to the device, and tap "Name" . Open the saved binary file in a hex editor like HxD
: Many versions of the VHM-314 lock the firmware , meaning serial pads might be disabled. If you cannot get an "OK" response after sending AT , the board may not support permanent name changes without specialized factory programming tools.
Open the (classic view) and navigate to Devices and Printers .
Note: While many Bluetooth modules use serial (UART) AT commands to change names, the VHM-314 utilizes specialized Bluetooth 5.0 chips. Changing its name typically requires advanced, hardware-level methods involving specialized programmers, rather than simple software commands. Why Change the VHM-314 Bluetooth Name?
(often branded as XY-BT) typically requires modifying the Bluetooth module's persistent storage, as these devices rarely support name changes via mobile app. The VHM-314 often uses chips like the OVC3860 or similar, which can be configured via computer. USB Programming (Preferred Method): Connect the to a computer using a USB cable.
